How to find the area of the cube face
Under the correct cube means a polyhedron all of whose faces are formed right quadrilaterals - squares. In order to find the area of a face of any cube that do not require heavy calculations.
Instruction
To get started is to focus on the very definition of a cube. It can be seen that any of the faces of the cube is a square. Thus, the task of finding the square face of the cube is reduced to the problem of finding the square of any of the squares (faces of the cube). You can take it any of the faces of the cube, since the lengths of all its edges equal.
In order to find the area of a face of the cube that you want to multiply between a pair of any of the parties, they are all equal to each other. The formula can be expressed as:
S = a2, where a is a square of side (edge of the cube).
Example: the edge Length of the cube is 11 cm, it is required to find its area.
Solution: given the length of the edge, you can find its area:
S = 112 = 121 cm2
Answer: the square faces of a cube with an edge of 11 cm is equal to 121 cm2
Note
Any cube has 8 vertices, 12 edges, 6 faces and 3 faces at the top.
Cube is such a figure, which is found in the home incredibly often. Suffice it to recall the game cubes, dice, cubes in various child and adolescent designers.
Many architectural elements have a cubic shape.
A cubic metre made to measure the volumes of different substances in various spheres of life.
Scientifically speaking, a cubic meter is a measure of the amount of substance that can fit into a cube with an edge length of 1 m
Thus, you can enter other units of measure of volume: cubic millimeters, centimeters, decimeters, etc.
In addition to the different cubic units of volume measurement in the oil and gas industry may use a unit - barrel (1 m3 = 6.29 barrels)
Useful advice
If Cuba is known the length of its edges, in addition to the face area, you can find other options of this cube, for example:
The surface area of the cube S = 6*a2;
Volume: V = 6*a3;
The radius of the inscribed sphere: r = a/2;
The radius of the sphere circumscribed around a cube: R = ((√3)*a))/2;
The diagonal of the cube (a line that connects two opposite vertices of the cube which passes through its center): d = a*√3
